简介:Charcot’s关节神经性关节病也称为Charcot’s关节病,1868年Charcot首先描述。此类疾病为无痛觉所引起,又有无痛性关节病之称,是一种较为罕见的神经营养性骨关节病,缺少特征性病理改变,易被误诊为其它疾病。笔者经治1例Charcot’s关节病误诊病例,原单位诊断为非特异性炎症改变。观察该病例的临床表现、病理学特点和影像学表现,并复习相关文献,旨在提高对该疾病的认识,减少或避免误诊。
简介:目的:探讨流式细胞术检测微小残留病(MRD)对判断儿童B淋巴细胞白血病(B-ALL)的预后价值。方法:回顾性分析2011年7月至2014年6月在我院初诊的196例B-ALL患儿,通过流式细胞术监测以上患儿诱导化疗第15天、第33天、第12周的骨髓MRD。结果:MRD阳性组中中危和高危分型的比例明显高于标危组,差异有统计学意义(P〈0.05);分析各时间点MRD,显示MRD水平越高,患儿的复发率越高,3年EFS越低。其中第15天MRD≥10-2组、第33天MRD≥10-4、第12周MRD≥10-3组的患儿预后不佳;经多因素分析显示,第12周MRD≥10-3为独立的预后不良因素。结论:流式细胞术检测MRD对儿童B-ALL具有重要的临床预后判断意义;需动态监测MRD,第15天MRD≥10-2、第33天MRD≥10-4、第12周MRD≥10-3的患儿预后不佳,需调整危险分层及化疗强度;第12周MRD≥10-3为独立的预后不良因素。
